Binghamite
is a mixture of chatoyant Chalcedony
(cryptocrystalline Quartz)
included with dense, parallel fibres of Goethite and/or
Hematite, similar to Tiger's Eye.
Because of this, it is also known as American Tiger's
Eye. Binghamite
has
also been called Cuyunite after the original discovery
at Cuyuna, Crow Wing County, Minnesota, USA. The
Cuyuna North Range mining district consists of a semicircular area 5 miles in diameter north-northwest of
Ironton, Minnesota. The ores are a typical banded iron formation that have been
metamorphosed and later concentrated into both brown and red Hematite ore. Mining
in the area was discontinued many years ago so Binghamite
has become fairly rare.
